UPON ADDITION OF A HIGHER AFFINITY LIGAND, REMARK 210 PACAP27, THE TRNOE CROSS PEAKS WERE SELECTIVELY ELIMINATED DUE REMARK 210 TO A COMPETITIVE INHIBITION OF THE SPECIFIC BINDING OF PACAP21 REMARK 210 TO THE RECEPTOR. ACCORDINGLY, THE SUBTRACTION OF THESE TWO REMARK 210 SPECTRA YIELDS TRNOE-RELATED CROSS PEAKS EXCLUSIVELY.
